The most user-facing Nouveau DRM driver change for Linux 3.19 is the initial GeForce 900 Maxwell series support as outlined this past weekend it's mode-setting well but doesn't yet provide any hardware acceleration for the new GeForce GTX 970/980 graphics cards.

This isn't the most exciting Nouveau DRM update in recent times, but at least there's a lot of other exciting features to Linux 3.19. For this article I ran some basic Nouveau DRM driver tests on Linux 3.18.0 stable compared to Linux 3.19 Git.

The two graphics cards being tested on the Intel Core i7 5960X rig were a GeForce GTX 680 and GTX 780 Ti, which is a limited selection given not many hugely pressing Nouveau DRM changes this round. On the user-space side was Ubuntu 14.10 upgraded with Mesa 10.5-devel Git and xf86-video-nouveau 1.0.11. The GTX 680 and GTX 780 Ti were both re-clocked to the maximum performance state possible on Nouveau before running into issues (illustrated above): 0a is the highest pstate for these two GPUs as of Linux 3.19.
